The Post-Install script is a customizable bash script used to install complex packages that cannot be installed through a package manager, require building from source, or need a specific order of operations. For these scenarios, use the Post-Install script. This script allows you to execute any command that can run on a Linux system (e.g., curl, unzip, tar, or git clone). The script is located below the package managers in the Environment Editor.
Since the Post-Install script runs during the build phase, its commands are only executed once and cached as part of your Capsule's custom environment.
No sudo Commands: Many software installation instructions may include commands like sudo apt-get install python-dev. On Code Ocean, sudo is neither necessary nor available and should be omitted.
Restricted Folder Access: The Post-Install script cannot access the /code or /data folders.
Working Directory:
The working directory for the Post-Install script is the root directory (/).
For example, if you create a folder with mkdir mylibrary, you can later refer to it as /mylibrary.
Accessing /opt:
The /opt folder is accessible during both the Post-Install script execution and reproducible runs.
For example, you can Use /opt to store source files or downloaded files, configure the package, and then add /opt to the PATH to make the package available during a Reproducible Run.
Environment Folder Size Limit:
The Environment folder has a 100MB size limit.
